RAIL-JOINT PATTERN.

.Specification of Letters Patent.

Patented Oct. 15, 1907.

Application led November 20, 1906. Serial No. 344,326.

To all whom it may concern:

Be it known that I, CHARLES AUGUSTUS WEEKS, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsyk vania, have invented certain new and useful Improve ment in Rail-Joint Iatterns, of which the following is a specification.

This invention relates to the art of manufacturing rail joints, and more particularly to the patterns elnployed in carrying out the process of casting rail joint members or plates.

To this end the invention contemplates a simple and practical construction of rail joint pattern embodying as a part thereof, adjustable means for accurately locating the bolt hole positions of the pattern to correspond exactly with the bolt hole positions in the rail ends to be joined by the rail joint. In this connection the invention has in view a construction possessing special utility in its application to patterns of the type employed in the manufacture of that class of rail joints known as step or compromise joints.

The function of the step joint or compromise joint is well known to those familiar with the art, but it may be observed that this class of joints is employed to connect rails of different heights and sections, so that the tops and sides of these dissimilar rails are supported in alinement. In the manufacture of this type of rail joint, the joint plates or members are generally made of steel or malleable iron castings, and of a design and configuration corresponding to that of the rail sections to be united, so that the difference in the height and section of the two rails is compensated for. In addition to the variance in height and section between the rail ends connected by a step joint, there is also a variance in the position and size of the bolt holes in the separate rails. This has ordinarily been provided for by making a new and separate pattern to cover each variation, and owing to the large number of rail sections in use having this divergence in position and size of bolt holes7 the eX- pense of making patterns for each individual rail joint is necessarily very large.

It is therefore the purpose of the present invention to obviate these objections to the ordinary method of manufacturing step or compromise joints employing new patterns for each joint, by providing a construction of pattern which can be utilized in the manufacture of rail joint plates or members for any of the ordinary standard rails of varying height and section and also having bolt holes in varying position and of different sizes` With these and many other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

The essential feature of the invention involved in the provision of a rail joint pattern with adjustable means for locating the bolt hole positions is necessarily susceptible to structural modification Without departing from the scope of the invention, but a preferred and practical embodiment of the latter is shown in the accompanying drawings, in which:

Figure l is a side elevation of a step joint pattern equipped with the adjustable core prints contemplated by the present invention, the view indicating in dotted lines the design and relation of the pattern with reference to the differential rails. Fig. 2 is an end view of one end of a pair of step joint patterns, embodying the present invention and illustrating the design and relation thereof to one of the rails shown in Fig. l. 'Fig 3 is a view similar to Fig. 2 of the correspondingly opposite end of the patterns and the other rail. Fig. 4 is a detail perspective view of a rail joint pattern constructed in4 accordance with the present invention, the view illustrating certain of the core prints removed to expose in full the adjustment slots. Fig. 5 is a cross sectional view thereof, the line of section including one pair of prints. view of one of the adjustable core prints. Fig. 7 is a detail sectional view showing a modified construction of adjustable core print mounting.

Like references designate corresponding parts in the several figures of the drawings.

In carrying out the invention no special change is required in the design or use of the ordinary patterns such as are commonly employed in the process of cast ing steel or malleable iron rail joint members or plates. Hence, for illustrative purposes there is shown in the drawings a design of pattern, designated by the numeral l, which is employed in the manufacture of step or compromise joints of the continuous type, which kind of joint essentially consists of oppositely arranged duplicate angle bars having main splice bar portions and integral base plate portions extending beneath and supporting the rail bases. In this class of joints the rest or supporting faces of the rail supporting bases for the separate rail ends are arranged at different elevations, that is, lie in different horizontal planes to provide for supporting the rail ends with the running surfaces of their heads in proper alinement.' All forms of step or compromise joints necessarily provide for securing that result, so it will be understood that the improvements contemplated herein are necessarily applicable to any type of step or compromise joint having side plates or splice bars for the bolts, and, in fact, to any cast rail joint plate where it is necessary to provide for locating the bolt hole positions with facility and accuracy.

Referring to the application of the invention shown in the drawings, each pattern l may be described as Fig. 6 is a detail rear perspective having a bolt plate member 2 for shaping the bolt plate member of the joint, and a base member 3 for shaping the rail supporting base of the joint, and in adapting the invention to the pattern, the same is provided in the bolt plate member 2 thereof` with a series of horizontal longitudinally disposed adjustment slots 4. These adjustment slots are arranged in the bolt plate member of the pattern within the range of all possible bolt hole positions in the separate rail ends, and are of a sufiicient length to comprehend any ordinary variations, longitudinally, in the position of the bolt holes;

There is associated with each adjustment slot 4 of thepattern what may be characterized an adjustable core print mounting, Which, in connection with the slot, provides for locating the bolt holes in the side joint plates to correspond with the positions and sizes of the bolt holes in the rail ends. The adjustable core print mounting consists of a pair ol core print members 5 and 6 arranged respectively upon opposite faces of the bolt plate member 2 of the pattern, and each provided at its inner side with an angular guide tenon 7 slidably fitting in the adjustment slot 4. The core print members 5 and 6 are preferably of an elliptical form corresponding to the .usual shape of the bolt holes in the rail ends, and to provide for a vertical, or up and down, adjustment for the prints, each of the same is so constructed that its guide tenon 7 is arranged out of center or eccentric to the center line of the core print, as may be plainly seen from Figs. 5 and 6 of thedrawings.` The opposite core print members 5 and 6 are designed to be coupled and fastened together by means oi a fastening screw, bolt or equivalent device 8 passing through suitably formed bolt or screw openings 9 provided therein.

From the construction described it will be seen that upon loosening the fastening connection 8 for the opposite core print members, each set of the same can be shifted to any desired position longitudinally of the adjustment slot 4, and then held fast in the adjusted position through the tightening of the fastening device. This adjustment of the core prints along the face of the pattern is made without removing the same, and provides for variations in position, lengthwise, of the bolt holes in the rail ends. To compensate for up and down or vertical variations in the bolt hole positions, it is simply necessary to loosen the fastening connection 8 sufficiently to permit the core prints to be reversed through partial rotation and then locked up in their reversed position. 1n this adjustment, the eccentric disposition of the guide tenons 7 necessarily provides for raising or lowering the core print bodies.

The distinctive feature in the mounting of the core prints resides in the provision of some definite mechanical means for permitting the same to be shifted in both longitudinal and vertical directions and then secured fast in their adjusted position, and While these results may be accomplished by different mechanical expedients, a practical construction has been described and illustrated. However, it will be understood that various changes in the form, proportion, and minor details of construction may be resorted to without departing from or sacriiicing any of the details or advantages of the invention, and in this connection a modification Which may be resorted to is suggested in Fig. 7 oi the drawings. Referring to this figure of the drawings, it

will be observed that under certain conditions it is possible to dispense with the separate under or inner core print members by using in place of the fastening screw 8 previously referred to, what may be termed a core print bolt 81L having at the under or inner side of the pattern a large head (it1 constituting the. under core print member. The bolt 82L carries at the opposite side of the pattern the core print member 5. In other respects the modified construction is similar to that already described so the same references will apply to similar parts in the two forms of construction-illustrated.

No claim is made herein to any particular Construction of moldthat may be employed in connection with the improved pattern, nor to any special manner of forming or setting up the mold, as it is to be under stood that the pattern forming the subject matter ot this case can be utilized in connection with any of the conventional molds or molding apparatus usually emv ployed in the manufacture of bars-for step or compromise rail joints; Hence, in this connection it need only be noted that in forming the mold the opposite sides of the herein described pattern are respectively utilized to impressv upon the opposite faces of the mold ing sand the contigui-ation of the outside and inside surfaces of` the casting, after Which the sand mold is usually baked as an entirety in preparation for the Final setting up and casting operation.
